THOMAS ANDREWS, OF ROCKAWAY, NEW ilElt't Elf, ASSIGNOR llll L Jn. V Lalo the MANUFACTURING COMPANY, OF ROCEZAVTAY, NEW' if, A CUEtPOlMtTION OF NEW' JERSEY.

ROTARY MOTOR FOR itUBE-CLEANIE To all whom it may concern:

Be it known that l, Triioiuas i i'nnni nvs, a. citizen of the United States and residing at ltockaway, county of llilorria. and Estate ot New Jersey have invented certain new and i'ise'lul .ll inprovenients in ltotaii'v ilfl otors for 'lube-Cleani-irs, oil. which the following is a specification.

The invention relates to iiinpreveineuts in rotative motors and has iartic'ular reference to that type of motor utilized in connection with automatic tube cleaners driven and controlled by means of the application thereto 01 fluid under pressure.

One object of the invention is the proriding of a casing hardngo; termed therein a eccentric chainliier adapted to receive a concentric HIOlUl' core carrying; a plurality ct wings, the objects of said wings being to assist in the rotation of said motor, and u'ieans whereby said wings during the rotation of the same utilize said fluid under pressure expansively.

Another object of the invei'ition is the providing of means associated with the relative or operative parts of a tube cleaner and particularly with the supporting structure of the rotative motor adapted to control the admission of fluid to said tube cleaner parts and the fluid passageways supplying said rotative core the ohjeet tl'iereojt' being; to autonn'itically control the admission ct fluid in said cleaner, said controlling means being so arranged that it controls the instantaneous starting and stopping of said motor.

In tl e following is described in eonnecti on with the accompanying drawings one enibodin'ient ot' the invention. the features thereof being; more particularly pointed out hereinatter in the claims.

lln the drawings, Figure l. is a longitudinal sectional view of the motor and oil? the casing therefor and oil? the tluid supply or teed controlling means; Fig. 2 is a cross sectional view on the line A B of Fig. 1.; fl 3 is a plan elevation, of the rotative motor core illustrating in connection therewith the relative positions of the driving wings as associated with the fluid supply passageways; and Fig. l is a cross sectional view of a modified term of the invention.

Similar numerals oi reference indicatesimilar parts throughout the several views.

In the drawings, 1 indicates a casing specification of Letters Patent.

Rotative core 3 has mounted therein wings 19 resting on CllRgQDfiIlly inclined surfaces 20 and provided with circular surface 21 conforming to the inner surface of bore 2. lfliaid wings 19 receive the fluid from ducts $23 which in turn communicate with ports fil al; formed in the wall of said cashing- 1. tlaid ports 9. 1: connect with lluid duct 25 in head a which communicates with fluid cha1nher it, said duct 25 being adapted to receive the initial iluid pressure supply it'roin any suitable source (said source is not shown herein as it does not form an essential part 01 the invention as any fluid generator may be readily utilized). After the tluid has expanded or caused the motor core 3 to rotate at a high rate of speed said fluid passes from said here or chamber 2 through exhaust port 96 in said casing l.

:lel erring to Fig. l of the drawings inotor core 2? is shown as mounted on sleeve 28 which is in turn mounted on shaft 29 to limit the longitudinal movement of said shaft in said casing, said shaft carrying the shut-oft disk 11 providing a means of controlling the admission of fluid under pressure into said fluid expansion casing 1. Said core 27 has pivotally mounted therein wings 3 the object of said wings being to provide means adapted to receive the fluid under pressure and assist in the rotation of said core. 32 indicates the fluid supply port and 33 the fluid exhaust port suitably located in the walls of casing 34.

The operation of the device is as follows: hen the device is inserted within the walls of a tube part of an auxiliary attachmenthereto engages said walis which causes piston 9 to open shut off disk 11 and permit fluid to enter ports 13 and 26, port 13 permitting said fluid pressure to be impinged against piston 9, and port 26 permits fluid to pass through ports 2% to the internal recesses of the motor casing, the function thereof causingthe instantaneous rotation of the motor and all parts rotatively associated therewith. The movement of the piston 9 draws shaft 10, which carries disk 11, with it thereby sealing port 25 which at this point causes the instantaneous stoppage of the rotative parts of the apparatus.

It is obvious that the device may be varied in many ways without departing from the spirit of the invention.

Vhat I claim and desire to secure by Letters Patent of the United States is 1. A device of the character described comprising a casing, a fluid expansion reception chamber formed therein, a fluid head, a shaft mounted in said casing and head, bearings for said shaft, a concentric core mounted on said shaft in said cylinder having cut therein a fluid passageway, wings pivotally mounted in said core, an auxiliary rotat-ive shaft, a piston head carried by said shaft, a chamber in said rotary head, and means actuated by said piston adapted to control the admission of fluid under pressure to said fluid expansion reception chamber.

2. A device of the character described including a fluid supply controlling means for rotary motor driven cleaners comprising a casing, a fluid expansion chamber therein, a core mounted in said chamber, bearings formed in said casing, wings pivotally mounted in said core, fluid passageways cut in said casing forming a means of communication between said aforesaid ports and said fluid expansion chamber, means formed on said head adapted to receive the hose end connection of a fluid supply, a shaft mount ed in said bearings, a piston head carried by said shaft and mounted in a recess formed in said casin a shut-oif disk mounted on the inner end of said shaft, and means act-uated from said piston adapted to adjust the position of said cut-0E disk with relation to said fluid passageways in said head.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
